+
+Description
+ This boundary condition provides a uniform fixed gradient condition.
+
+ \heading Patch usage
+
+ \table
+ Property | Description | Required | Default value
+ uniformGradient | uniform gradient | yes |
+ \endtable
+
+ Example of the boundary condition specification:
+ \verbatim
+ myPatch
+ {
+ type uniformFixedGradient;
+ uniformGradient constant 0.2;
+ }
+ \endverbatim
+
+Note
+ The uniformGradient entry is a DataEntry type, able to describe time
+ varying functions. The example above gives the usage for supplying a
+ constant value.
